|M PRrovED DOOR-.HANG ER.

Specification forming part of Letters Patent ANo. l04,064, dated June 7', F570.-

fo all whom it may concern:.

Be itknown that I, SAMUEL P. ROBINSON, of Canterbury, in the county of Windham and State of Connecticut, have invented a new and Improved Mode of Constructing Door-Hangers, which'I denominate a Self-Clearing Door.-

YHanger; and I do hereby declare. that the following is afulland exact description ofthe construction andoperation of the same, referencebeihng had to the anneked drawings, making apart of this specification, in which- Figure 1 is a front elevation securedl to a door and resting on a section of track as in section parted through the cent-er longitudi# 4 nally, as indicated by the red lines y g/ in' Fig. 1.

lLike letters 'refer te like parts inthe draw'- ings.

a represents the frame, which is attached to the door b by screws d d d d, and supports'the' truck c. 4e represents a section of track secured to the building. Thepin or axis f,fupon which the truck revolves, is set in the mold andthe frame cast onto one end of it, and the truck c held in position by upsetting the other Fig. 2 is a reverse of Fig. l, secured to 'the doorin same manner; and Fig.*3, a cross-- :ning of.

end against .thewasher g. The friction-truck cV has beveled flange upon its periphery, instead of the ordinary straight flange or groove.

With ordinary truck-door hangings, doors are frequently thrown from the track by the displacement of the ends .of the bars or rods put up in sections, caused by warping or swelling of the lumber used in the construction '0fthe building to which the track is secured, -drawing of nails and screws byA expansion and contraction of the track, and 'other causes. By constructing the friction-truck c. in the manner herein described,'the door is crowded back to its place, instead of rising overthe4 ends of 'displaced sections of track vor run W'ha-t I claim as my invention, and desire to 'secure by Letters Patent, is-

The combination of the beveled truck c with the frame a, substantially as constructed, and for the purpose specified. Y y
